2 Background The National Association of Healthcare Fire Officers (NAHFO) is an organisation that acts as a national voice for all those associated with healthcare fire safety. Having identified that there was no recognised or adopted ‘cradle to grave’ standardised systems for inspecting and managing fire doors in healthcare buildings, a NAHFO London Working Group was formed in 2019 to write a paper intended to assist in the development of systems for doing so. Having agreed on a final version of the paper in 2020, the words have been used as the basis of this Reference Document with the intention of sharing healthcare building fire door inspection best practice to a wider audience.
Foreword The National Fire Chiefs Council (NFCC) has always promoted the critical role that fire doors play in protecting us when we are asleep and when we are at our most vulnerable. Recent tragic events have yet again reinforced the important role that fire doors have in saving lives and protecting property, which is especially important in healthcare premises when doors are correctly designed into the fire strategy. Healthcare premises are buildings where we expect people to be safe and protected from fire and this guide will help ensure that fire doors play a key role in that expectation. This guide will assist in ensuring that fire doors are correctly specified, procured, installed and well maintained throughout the life-cycle of the installation. It represents a positive step forward in fire door design and maintenance and will assist both NFCC and NAHFO to continue to help healthcare landlords comply with regulation and crucially assist in keeping some of the most vulnerable people in our community safe from harm.

4 How to use this document Fire safety advisors, fire door inspectors and other fire industry professionals will hopefully find the whole document of interest, but it is also intended to be largely read and used by a cross-section of those whose involvement with fire doors may only be brief and incidental. For that reason the information is split into 4 distinct ‘easy to access and read’ sections: Section 1 covers new fire doors in healthcare buildings and related ‘Type 1’ inspections; so this section is likely to be of most interest to those involved in new build and major refurbishment projects involving the installation of new fire doors and particularly for those with the responsibility of providing and receiving new fire doors in a compliant state. Section 2 deals with different options and approaches for ‘Type 2’ inspections of existing fire doors, often where very little written information regarding their specification, performance or fire compliance is available or exists. Section 3 deals with the ongoing, functional ‘Type 3’ inspections of fire doors where they are known to be fire compliant to a suitable and sufficient standard for their location and usage, having already been either ‘Type 1’ or ‘Type 2’ inspected. Section 4 deals with creating and sustaining a robust Fire Door Management System for achieving and maintaining long term fire door compliance in a Hospital Trust or other healthcare organisation.

0.4 Fire doors are the most frequently used and often abused element in a fire compartment and the ways in which they are inspected can be manifold and complex, influenced by a number of factors including the age, usage and criticality of the doors, combined with the size, function and fire & evacuation strategy of the building in which they are installed. It is very important that these protection measures are understood and correctly inspected and maintained if buildings are to perform as expected, should fire break out. By their very nature they are ‘passive’ until there is a fire, and only then will their fire performance in-situ be demonstrated. Fire doors are complex assemblies that have to comply with a range of technical standards. Image courtesy of Lorient UK Introduction 7

Type 2: A robust but potentially pragmatic and flexible one, which could be purely visual or may contain an invasive element, carried out on existing fire doors in occupied buildings where there is often no evidence of performance and where no, or little, information exists. This type of inspection is to comply with the Regulatory Reform (Fire Safety) Order 2005 (hereafter referred to as the FSO); assessing if the condition of each fire door is suitable and sufficient in terms of meeting and maintaining the requirements of both the building’s fire risk assessment and its fire evacuation strategy to protect relevant people and ensure safe evacuation or protection in the event of a fire.

0.6 Please note that the definition of ‘healthcare building’ in this document is “any building used by the NHS and other healthcare providers” rather than the narrower Firecode definition of “a hospital, treatment centre, health centre, clinic, surgery, walk-in centre or other building where patients are provided with medical care by a clinician”.

Introduction 10 Image courtesy of Golden Thread Fire Delay 0.8. As per Dame Judith Hackitt’s recommendations in her independent report following the Grenfell Tower fire (please see the ‘recommended reading’ section), all fire door inspections should be electronically recorded using software such as Bolster, that have the flexibility to accommodate the 3 inspection Types outlined in this document, to provide a ‘golden thread’ of information that can be used as the foundations of a robust electronic ‘paper trail’ for managing remediation and future ongoing inspections, to ensure they are maintained in a suitably compliant state in keeping with statutory requirements, do not deviate from the Primary Test Evidence, GFRA or product-specific BS EN test and that LPCB or equivalent audited certification, covering their fire compliance, remains valid.
Section 1; Type 1 Compliance Inspections of New Fire Doors 1.1 If the fire door, as a doorset, is manufactured and installed under Third Party Certification Schemes and procured in line with Firecode HTM 05-02 and any special requirements for its location, then the standard should be satisfactory as both the manufacturer and installer will systematically have a percentage of their doors subjected to regular audits, inspected by the Certification Body using a comprehensive inspection form and using calibrated measuring tools. The door manufacturer’s latest design drawings and installation details are normally used as a reference as to how the door should have been made and installed. The inspection of each element by the Certification Body should be both detailed and robust and doors under such schemes should have stickers or plugs to identify its rating and who manufactured and installed it so that full traceability is possible. Companies installing, inspecting, maintaining and repairing in certification schemes can typically issue a uniquely numbered 3rd Party Certificate of Conformity.

Section 1; Type 1 Compliance Inspections of New Fire Doors 12 1.2 It may be prudent for those responsible for the building handover to do spot checks to verify that everything is to the Scheme standard. This could include invasive checks that would be difficult to conduct later, such as the interface between the frame and wall (i.e. surrounding substrate). It would also be appropriate to ensure that a complete electronic ‘paper trail’ has been compiled, including for each door type valid test evidence or GFRA in the manufacturer’s current scope of approval, together with a UKAS or equivalent Certificate of Conformity for the installation, in a format easily accessed and user friendly, providing a ‘golden thread’ of information necessary for ongoing ‘Type 3’ inspections. 1.3 If the door installers are not in a Third Party certification scheme then inspections of the doors to a similar standard will be required by someone with the competence to do so. Who is going to conduct the inspections should be agreed and arranged at the procurement / pre-tender stage so that they can commence during the build contract, as checking purely at handover is too late to deal with the majority of potential non-compliance issues.

1.4 Establishing Competence: The FSO identifies competent persons as those with sufficient training and experience or knowledge and other qualities to enable them to fulfil their role and responsibilities. Firecode HTM 05-02 defines as “a person recognised as having sufficient technical training and actual experience, or technical knowledge and other qualities, both to understand fully the dangers involved, and to undertake properly the statutory and Firecode provisions”. Fire door inspection competence needs to be appropriate to the complexity of role, level of responsibility and associated life safety risk in healthcare premises; therefore relevant third party accreditation, such as LPS 1197, is strongly recommended for any company or individual undertaking Type 1 and Type 2 inspections, together with professional indemnity cover. As a guide to those responsible for appointing an inspector, those undertaking the inspections are likely to have a background in fire door testing, manufacturing or installing and should have a thorough understanding of fire doors in the context of Firecode HTM’s 05-01, 05-02 and 05-03, The FSO, Building Regulations, British Standards, Approved Codes of Practices and managing risk in healthcare premises. Please note that the BSI is currently in consultation for BSI Flex 8670 v1.0 Built environment – a standard intended to specify competency requirements for individuals working in the built environment to support the development of an overarching framework for the competence of individuals working on higher-risk buildings as defined within relevant legislation.

Section 2; Type 2 Compliance Inspections of Existing Fire Doors 2.1 Type 2 Inspections are undertaken on existing fire doors, sometimes referred to as ‘notional’ fire doors, where little or no information currently exists or is readily available. Such inspections play a vital role in a hospital Trust or healthcare organisation assessing its existing fire doors in terms of fire compliance, and understanding if those falling below the required performance level have the potential to be remediated to an acceptable certifiable standard, or need to be replaced. Image courtesy of Golden Thread Fire Delay The stated fire performance of a door, given by its affixed sign, should not be ignored or thought worthless, as when the door was installed, potentially before certification schemes existed, it may have been the only evidence of performance required to confirm that it had been designed, procured, manufactured and installed competently. Section 2; Type 2 Compliance Inspections of Existing Fire Doors 27
Section 2; Type 2 Compliance Inspections of Existing Fire Doors 28 2.2 They need to be carried out by competent persons (please see 1.4 above), who in addition to knowing how to inspect a new door in healthcare environments should also be thoroughly familiar with industry Approved Repair Techniques on existing doors. The inspection should be recorded, preferably electronically, with a pass / fail criterion. Competently assessing older doors is an important skill in the support of responsible spending, but critically the level of inspection needs to be suitable and sufficient for the type and use of building and location (risk rating) of doors. Because the standard of inspection may be audited or questioned by other stakeholders, a written set of inspection protocols, outlining how the doors should and have been inspected, is advised. Image courtesy of Golden Thread Fire Delay This type of inspection is likely to be the most onerous with regards to the research needed, as the inspector may become directly accountable for the fire door performance assessment. Professional Indemnity insurance is therefore required and evidence should be obtained by the Trust or healthcare organisation before such inspections take place.
Fire Risk Assessments, following a Type 2 inspection having occurred, may consider active fire protection measures in place, such as water mist systems, that would reduce the risk and therefore the required compliance levels of doors. This would be in keeping with recent Government guidance, Building a Safer Future, December 2018, which states that: “Buildings should be considered in a holistic manner and mitigation measures should be layered appropriately based on the use of the building and the risks posed” 2.3 An up to date set of fire strategy drawings for the building is essential to ensure that the ‘fire doors’ to be inspected are located in a fire compartment wall and are therefore required to have fire and smoke resisting properties. Image courtesy of Golden Thread Fire Delay Section 2; Type 2 Compliance Inspections of Existing Fire Doors 29
Section 2; Type 2 Compliance Inspections of Existing Fire Doors 30 2.4 In the absence of information on the actual doors being inspected, those undertaking Type 2 inspection evaluations should not only be comparing its condition in compliance with Firecode 05-02 2015 as given in Appendix C, page 73 (Please see page 57 of this document), but also the importance of the doors in terms of what they are protecting (criticality factor) and therefore what level of compliance is suitable and sufficient and which doors should be given priority in terms of remediation or replacement. This needs to be expertly assessed by a fire safety advisor responsible for the building; for example ‘sanitary accommodation’ rooms in mental healthcare settings may be deemed as hazard rooms due to patients having the propensity of using such rooms as a location for starting a fire. By doing so a fire door ‘action priority’ report can be established, leading to cost-effective, measured fire door improvement to reduce risk from year one; not only actual risk from fire for people, the building’s fabric and activities but also in terms of protecting the Trust or organisation and its management, as it provides documents that can be shared with external auditors to demonstrate consideration of FSO Articles 17 and 38, as part of a coherent fire door management system with a commitment to actual year on year improvement.

2.5 The limitations of remediating existing doors without previous certification or known fire performance needs to be fully understood, and careful consideration should be given to the extent it is acceptable and even economically sensible to remediate doors such as those manufactured with rebates prior to the existence of intumescent seals. Those seeking to do so should also be conscious that asbestos was widely used in fire door manufacture prior to 1980. 2.6 It is good practice for those carrying out ‘Type 2’ inspections, especially in the absence of an installer’s label, to affix uniquely numbered, dated, identification stickers to advise that a competent inspection on the door has taken place, who inspected them and to help locate and identify individual doors referenced on drawings and / or fire door schedules. Those undertaking Type 2 inspections under schemes such as LPS 1197 can issue a 3rd Party Certificate of Inspection, that can be used as the foundations of a robust ‘paper trail’ for potentially managing certified remediation and future ongoing inspections in keeping with statutory requirements.

This can be ascertained if it has labels or identification plugs to provide specification traceability, otherwise it may be expedient to remove ironmongery such as the lock casing in order to do so. Door leaf thickness; will often help to determine if the door is a fire door and if its rating is as assumed and required. A 30 minute timber door is normally approximately 44mm thick – a 60 minute door being approximately 54mm. This is not always the case, for example some European based manufacturers use 38mm cores for 30 minute and 62mm cores for 60 minute and hygienic faced vermiculite-cored fire doors tend to be 40mm thick irrespective of fire rating, but doors should not be assumed to have ratings if they are not to the guide thicknesses and no information on the doors exist.

The use of polyurethane foam without unambiguous test evidence should be treated with suspicion. In the absence of manufacturer’s information it is recommended to follow guidance given in BS 8214:2016. Such gaps will often be hidden by architrave and a decision will need to be made whether or not to investigate the gap for compliance. There are three suggested options: Image courtesy of Golden Thread Fire Delay 1. There is confidence (reputable evidence?) of the gap being correctly sealed so no action required. 2. There is no evidence or confidence of compliant gaps, so 10% of architraves are removed for inspection, which will be extended if a number are found non-compliant. 3. There is no evidence or confidence, but the location is assessed as being ‘low risk’ and therefore potential non-compliance is not thought to be significant.

Double swing action via a transom concealed closer and pivot assembly, often used where reduced ligature points are required or for a retrospective installation, have similar traits and should be similarly inspected. For both generic types there is also the need to check that the pivot assemblies and transom closer housing have a 2mm thick intumescing liner installed throughout the top and bottom pivot recess, which would probably have been required for the doors to pass their fire integrity test.

All locks should be fire tested and compatible with the door’s fire test evidence; the retro-fitting of code locks and other types of locks can compromise fire test compatibility and their specification should be investigated and assessed. Intumescent protection may be required between the lock and the door leaf and the frame strike plate to reinstate fire performance, especially on 60 minute doors and this should also be investigated. The functionality of the handle should be inspected; also the height of the handle for Part M compliance, i.e. approximately Intumescent lock protection should 1 metre floor height. be bespoke to the lock and not created badly and inadequately using Check that any post COVID-19 retrofitted hinge pads. hygiene handles have the required fire test evidence for use on a fire door.

A pragmatic view of existing glazing providing up to 30 minutes integrity may be allowable in the short term for low risk locations if the glazing system appears to be factory fitted, is free from damage, tight in the frame and does not have any of the glazing bead missing or damaged, but it should be recorded as a potential ‘weak spot’ to be addressed. Any obvious signs of non-conformance such as ad-hoc mastic around glazing should not be tolerated and necessitates replacement. All single sheets (i.e. not laminated panes) of fire-rated glass give an ‘integrity only’ rating and extra care should be taken when assessing glazing in areas where temperature and / or acoustic insulation is also a requirement, particularly refuge areas. In such locations there may be a need to fit an intumescent laminate glazing system to provide the required insulation and acoustic properties. It should also be noted that “only glazing that provides a minimum period of fire resistance of 30 minutes (integrity and insulation) may be provided on circulation spaces that give a single direction of escape”. Firecode HTM 05-02 3.32. It should also be inspected in terms of Part M and Part K compliance.
